Simple Lisp to convert inches to millimeter

[Dizzle517]

Ok I'm new to LISP. I'm trying to get a simple LISP to convert a number in inches to mm and and also the other way around a number in mm to inches.

 

Thanks for the help

why do you want a LISP? Isn't the built in calculator (with its own conversion tables) sufficient?

[Dizzle517]

It is sufficient but I'm just working on using LISP and I was just wondering if there is a LISP for that.

Do you mean you want to change a dimension that is in inches into mm and vice versa? If not then, inches to mm:

^c^cUserr1;\$M=$(*,$(getvar,userr1),25.4)

mm to inches:

^c^cUserr2;\$M=$(/,$(getvar,userr2),25.4)

They're not lisp but they will return the value of the dimension in the command line.

 

Updated: I didn't like USERI1 that much so I changed it to USERR1.

I've moved your question to the Lisp section. For best results, try to post your question in the correct area of the forum.

(defun i2m (i)
 (* i 25.4)
)

 

Usage :

(i2m 1.0)

should return 25.4

(defun mm-to-inches (mm)
 (/ mm 25.4)
)

Excuse me for saying so, but it seems that this is a very simple conversion to be asking for. Are you new to programming as well? Are you availing yourself of the tons of help on this and other related sites?
